Geckos in your Mediterranean garden: allies worth protecting

On a summer evening, on a terrace in Monte-Carlo or Cap-d'Ail, a small lizard pressed flat against the wall beside the lamp is biding its time: it is a gecko. The first instinct is often to get rid of it. That is a mistake: geckos are valuable allies in a Mediterranean garden, provided you can recognise them and do not expect more of them than they can deliver.

Two geckos to recognise on the Riviera

The Moorish gecko

This is the most common gecko on the Côte d'Azur. Stocky and flattened, it reaches about fifteen centimetres including the tail. Its grey-brown skin, covered in small tubercles, gives it a spiny look, and its broad toes, lined with adhesive pads, let it run across a wall, a ceiling or a window pane. It hunts mainly at night but readily basks in the sun on a low wall, even in winter.

The Mediterranean house gecko

Smaller (around ten centimetres) and more discreet, the house gecko has pinkish, almost translucent skin dotted with dark spots and small warts. Mostly nocturnal and found only in patches along the coast, it frequents outdoor lights, the underside of roof tiles and cracks in old walls.

Two harmless species

Contrary to a belief that still lingers in the south of France, the Moorish gecko is not venomous and does not attack people or pets: it will only nip if you grab it. Caught by the tail, it sheds it to escape; the tail grows back, but the animal loses part of its reserves in the process.

What geckos bring to your garden

Geckos are insectivores. At night they position themselves near lamps, where insects gather, and catch moths, flies, mosquitoes, small beetles and spiders. A lit terrace can host several individuals hunting every evening, with no products and no upkeep.

Their presence is also the sign of a garden rich in shelter and insects. In neighbouring France, native geckos are listed among protected reptiles: destroying or capturing them is prohibited.

Their limits: a gecko is not a treatment

They complement pest control without replacing it:

• The tiger mosquito bites mainly during the day, while geckos sleep, and breeds in tiny amounts of standing water (saucers, gutters, drain covers). Only removing these breeding sites, backed up if necessary by targeted treatment, brings the pressure down: see our page on the tiger mosquito and how to prevent it.
• Rodents are not prey for a gecko. Beware of confusing the two: gecko droppings, dark and elongated, end in a white tip; mouse droppings do not, and are usually found along skirting boards or in cupboards. If in doubt, see our page on rats and mice.
• Cockroaches, Argentine ants, Asian hornets: each calls for its own diagnosis.

The mistakes that drive geckos away

• Spraying a broad-spectrum insecticide on façades and garden walls: you wipe out their food and expose them directly.
• Setting glue boards outdoors or in a garage: geckos get stuck and die.
• Dismantling dry-stone walls and filling every crack in the garden: seal the openings of the house, but leave the garden walls their crevices.
• Letting a cat hunt freely at night: cats are among their main predators in town.

Living together day to day

A gecko has come into the house? No cause for concern. At dusk, switch off the lights inside, open the window and turn on the outdoor light: it will leave of its own accord. Otherwise, cover it with a jar, slide a sheet of paper underneath and release it at the foot of a wall. Mosquito screens on bedroom windows prevent these visits, and those of mosquitoes too.

Droppings on the terrace? They build up beneath favourite hunting spots; rinsing with water is enough. To have fewer, rethink your lighting: a warm-white LED, pointing downwards and switched off when not needed, attracts far fewer insects, and therefore fewer geckos, than a cold white light.

Tackling real pests without sacrificing useful wildlife

At Monaco Pest Solutions, integrated pest management starts with a free on-site audit: visual and acoustic inspection, species identification, mapping of entry points. The personalised action plan then sets out a graduated treatment: mechanical first, then biological, and only after that targeted chemical treatment, using approved products applied by Certibiocide-certified technicians. Pets and biodiversity are taken into account at every stage: that is our four-step method.

In practice, we remove mosquito breeding sites rather than spraying the hedges: geckos, bees and other beneficial species all gain, as our article on Mediterranean biodiversity and pollinators explains. Every intervention ends with a report including photos.
